Abstract. In this work, we study inverse resonance problems for the Schrödinger operator on the real line with the potential supported in [0,1]. In general, all eigenvalues and resonances can not uniquely determine the potential. (i) It is shown that if the potential is known a priori on [0, 1/2], then the unique recovery of the potential on the whole interval from all eigenvalues and resonances is valid. (ii) If the potential is known a priori on [0, a], then for the case a > 1/2, infinitely many eigenvalues and resonances can be missing for the unique determination of the potential, and for the case a < 1/2, all eigenvalues and resonances plus a part of so-called sign-set can uniquely determine the potential. (iii) It is also shown that all eigenvalues and resonances, together with a set of logarithmic derivative values of eigenfunctions and wave-functions at 1/2, can uniquely determine the potential.
